TRANSMISSION THROUGH EXTREME MODEL ATMOSPHERES
The transmission of infrared energy in the 2.5- to 3.1-micron spectral region has been calculated for four model atmospheres representing average and extreme latitudinal and seasonal variations. Transmission values are shown for slant paths outward through the earth's atmosphere as a function o...

Summary: | The transmission of infrared energy in the 2.5- to 3.1-micron spectral region has been calculated for four model atmospheres representing average and extreme latitudinal and seasonal variations. Transmission values are shown for slant paths outward through the earth's atmosphere as a function of zenith angle and starting altitude of the ray path. Values have been calculated, using the Elsasser and Goody absorptionband models, for absorption by carbon dioxide and water vapor, respectively. The spectral resolution is approximately 0.006 micron. From altitudes above 10 km., maximum transmission is obtained through the tropical model atmosphere and minimum transmission is obtained from the artic summer model. From altitudes below 10 km., the extreme atmospheres are the artic winter model (maximum transmission) and the tropical model (minimum transmission). (Author) |
